This paper presents an extension to the ePresence Interactive Media webcasting infrastructure to support real-time voice and video conferencing for a few attendees while concurrently streaming an event to many others. We emphasize the tools for enhancing awareness of the remote attendees in the lecture hall or seminar room, and for facilitating communication between remote attendees and the lecturer. We present preliminary results of a field study of the use of this environment for a multi-campus university class.
